We report direct resonant diode pumping of a 1.6-micrometer-Er3-doped bulk solid-state laser. Using a 1470-nm-single-mode diode laser module to pump the ErYAG rod, an absorbed photon conversion efficiency of 26 has been obtained in this initial experiment. Analysis of the diode-pumped solid-state laser input-output characteristics suggests that the obtained slope efficiency can be doubled through the reduction of intracavity losses and pumping efficiency improvement.
